Our Tekto Flat Bioclimatic system, one of our collapsible aluminum bioclimatic ceiling systems, is made entirely of aluminum and can operate completely flat. Since there is a stream system on 4 sides, water discharge is carried out through 4 channels and no water leakage occurs. Our flat tecto bioclimatic system works with a single engine system and the panels start to open at a slight angle, they can be stopped and retracted at the desired point. In this way, the system provides the pleasure of meeting the sun in the open air.
